Object-oriented development life cycle: which ordering and iteration pattern best characterizes the process?

Introduction / Context:
Object-oriented development commonly embraces iterative and incremental practices (e.g., the Unified Process, agile methods). While work is conceptually divided into analysis, design, and implementation, modern practice cycles through these phases multiple times, refining the system with each iteration.

Given Data / Assumptions:

• There are three core phases: analysis (understanding the problem), design (architecting the solution), implementation (coding and integration).
• Iterations allow feedback, risk mitigation, and continuous refinement.
• Phases are typically presented in order for clarity, even though feedback loops occur.

Concept / Approach:
Choose the option that retains the logical ordering but explicitly acknowledges multiple iterations. This mirrors iterative, risk-driven processes: start with analysis artifacts, derive design models, implement a slice, evaluate, and repeat with deeper detail or broader scope.

Step-by-Step Solution:

Verification / Alternative check:
Practices like RUP and many agile variants iterate through analysis–design–implementation within each sprint/iteration while preserving a sensible flow inside the iteration.

Why Other Options Are Wrong:
Single pass ignores iteration (learning).
Any order obscures the normal conceptual progression and can cause confusion.

Common Pitfalls:
Thinking iteration removes discipline; in fact, each iteration still follows a structured mini-cycle.

Final Answer:
Analysis, design, and implementation steps in the given order and using multiple iterations.
